Y A lfurther object of this invention is toprovide a means for packingfrangible articlesV which will be relatively simple in construction,compact, ofpleasing appearance, and very durable in use'.

With these and other objects in view, which will'appear as thevdescription proceeds, there has been illustrated in the accompanyingdraw,- ings one yform in which the invention may be convenientlyembodied in practice. l i `Irv thevdrawings, whereinlike reference nu-`merals designate like parts throughout the severa-l views: t Y 'l Figurel is a sectional View of an opened container, for packages offrangible-,disc-like viiying targets, constituting and embodying thefeatures and principles of this invention; Figure 2 `is a top view ofthe same; i Figure 3 is a side view of a partition member;

The frangibe` article selected to illustrate the features and principlesof this-invention in re:

spect -to an improved means for packing the samev comprises a targetsimilar 'to Ytheftarget shown and-'described in a copending applicationSerialltlh. 3,718,857 filed February 20, i946). Such forms of targetsare generally yfrusto-conical in shape "and, by being hollow and havinga vbase rimv Il adapted to -t over a rst vertical'shouh der L2 and reston the upper surface I3 ofthe base rim Hof a similar target, are adaptedto be nested together to form a vertical -pileoftargets as illustratedin Figure '7.- In this instance thirteen targets are shown nestedtogether and in direct contact with each other at their base rims, .butit will be understood that more. or less than, thirteen targets may beso nestedto'- gether in the manner herein shown if it is so desi-red. f''f'After' nesting a plurality of v targets together, a narrow band, -or-cord, `of material i4, vsuch as a com-mon rubber elastic ba-nd,visplaced over and about the same from one end `of'the 'pile totheother-:so as to "resi-l-iently and -rmly bind the plurality oftargets together and against each other.l --A strip of, :preferablycorrugated, cardboard 15,- with the corrugations thereof prefer-i ablyonthe inside and extending lengthwise of the package, is then Wrappedtransversely about the sides' ofthe pile of nested targets, as indi;cated in Figures 5 and 6. The end edges I6 `and Il of the cardboardstrip l5 overlap to some expoints, as at 22, 23 and 24, 25 respectively,to;y

position the pile of targets within and spaced from the ends of thepackage so formed'. Prefff erably the band I8 is disposed about thepackage f to lie in these crimped-in portions and to extend,

along one side of the package ,over the overlapped end edges I6 and I Iof the strip I5.

is also preferable that one crimped l,portion atv each end of thepackage be disposed at the overlapping end edges I6 and II of the stripvI'5-to=- form an interlock between these ends to assist in preventingthis strip from unwinding. As shown, it is preferable to vstart 'thebent, or crimped-in, portions 22,v 23 at the top edge 26 of theuppermost target of the pile, and to start the bent, or crimped-in,portions 24, 25 at the bottom edge ofthe base rim, or bottom, II, of thelower-most target of the pile so that the pile of targets will be heldbetween these crimped-in portions and be spaced from the protruding endsI9 and 2| of the package so formed.

By so packing a plurality of nested targets, each directly in contactwith the other, a pack.-` age is formed which, in this instance, iscylin- -`adjacent end of the container.

locking partitions 38 and 39 of corrugated cardboard with thecorrugatlons disposed vertically in respect to the packages, which formvertically disposed pockets 4I in which the packages of targets arevertically slipped, and the Walls o1' which rmly engage these packagesof targets. The lengthwise partitions 38 extend at each of their endsbeyond the cross-wise partition 39 adjacent thereto to snugly engageagainst the The cross-wise partitions 39 likewise extend beyond thelength- .'fwisel partition38 adjacent their ends to snugly engageagainst the adjacent side of the container. .-Thisconstruction forms aprotecting space 42s`urrounding-V the packages of targets between e thepartitions 38 and 39 and the ends 28, 29 and thesides 3I,-32 of thecontainer, and the partidric'al in form, and has its ends I9 and 2|spaced Y from the respective upper and lower-most target of the nestedpile thereof, whereby the end targets are protected against contact withany other article when the package is seated on either of its ends, andare also protected against contact with any surface upon which thepackage may be dropped, and the inner targets of the pile are relievedfrom shattering shocks which might be imposed upon the package. Due tothe provision of a rubber elastic band I4 about the nested targets andthat the cardboard strip I5 while tightly wrappedthereabout'frictionally engages this band I4. an added means Aisprovided to resist endwise slipping of the pile of targets in respect toits wrapper. the cardboard strip I5. "Ihe provision of a rubber elasticband I8 to constantly and resiliently urge the crimpedin portions of thewrapper, or cardboard strip I5 into tight engagement with the targetsenfolded thereby, insures that no side slip will result between thewrapper and the targets or between the targets themselves, but willallow some expansion of either, or both, of these crimped-in portionslengthwise of the package to absorb any shocks imposed thereon when thepackage is dropped.

After packaging each pile of nested targets as above described they aredisposed in a container illustrated in FiguresV l-4 inclusive, and whichcomprises a rectangular box. preferably made of corrugated cardboardvand having ends 28, 29, sides 3I`, 32, end cover and bottom aps 33, 34,side cover and bottom naps 35, 36, and a sepa-A rate cover and bottomend flap spacer 3'I. The end cover and bottom flaps 33 and 34 with thespacer 3l form a flat inner surface and with the side cover and bottomflaps 35, 36 which abut at the center form a double thickness wall ofcorrugated cardboard at the top and bottom of the container.

The container also includes two sets of intertions 38'a'nd 39 reinforcethe container sidewise "'The sets of interlocking partitions 38 ande39are superimposed one above the other, being sep'- 'arated by a loosehorizontal partition 43, also of corrugated cardboard with thecorrugatlonsrdi'sposed transversely across it, upon which the upperplurality of packages are seated; When filled with packages of targets,the container is closed at its top by the respective cover flapsV andsuitably sealed with gummed paper disposed along the jointure of theabutting side flaps 35', 33. When closed, the container, due to thever--y tical reinforcement of the partitions which,` with the'horizontal partition 43, extend betweenl vthe top and bottom cover partsand arer engaged thereby, resists crushing forces to protect thepackages of targets therein. When again opened, the rst layer ofpackages of'targets may be re'- moved intact. one at a time, withoutdisturbing the others. Preferably, and to insure that th packages oftargets do not slip lengthwise-in the pockets 4I, theheight of thepartitionsl 38 and 39 is substantially equal to the height ofthepackages from one `end I9 to the'other end l2| thereof, so vthat thesepackage ends will be en` gaged by the top or bottom double wall ofl thcontainer and the horizontal partition 43far1d firmly held in place. 'fj

By means for packing frangibl'e 'articlesas above described, a pluralityof the articles',l in

this instance the disc-'like flying targets II,`are

walls 'and the'partitions therein before the pack-J ages are effectedthereby and then by the pro-y truding ends I9 and 2l of the packages.`While there has been shown and described hereinone means for packingfrangible artiJ cles, it is to be understood that the inventionA may beembodied in other forms without depart` ing from the spirit andessential attributes thereof. It is therefore desired that the presentembodiments be considered in all respects asl illustrative and notrestrictive, and it will be further understood that each and every novelfeatureA and combination thereof, present in, or possessed by, the meansherein disclosed, forms a partof the invention included in thisapplication.

What is claimed as new and for which it is desired to secure LettersPatent, is:

l. Means to package a plurality of frangible articles'nested together incontact with each other in the form of a pile, a band of material 10extending lengthwise about said pile of articles, a wrapping ofcrushable material, such as corrugated cardboard, wrapped transverselyabout aboutg'the wrapping and disposed between the 20 upstandingportions and upon the bent over portions to hold it about the pile ofarticles and to suspend said articles between its ends.

2. Means to package a frangible article comprising a wrapping Vofmaterial encircling the article with its side edges overlapped andhaving end portions extending beyond the upper and lower ends of saidarticle, said extending end portions being crimped inwardly against theperipheral edge of the adjacent end of said article at peripherallyspaced apart points, one of the crimped-in points being disposed at theoverlapped joint of the side edges to interlock them the remainingportion of the extended wrapping ends being left projecting beyond thecrimpedin portions to protect the article against endwise shocks, andmeans to resiliently press the crimped-in portions of the wrapping atboth ends of the article against the adjacent end thereof.
